MEASUREMENT OF FIRM‐SPECIFIC TECHNICAL EFFICIENCY: A COMPARISON OF METHODS
比较了测量企业技术效率的多种方法，发现静态确定性方法会高估效率随时间的变化，并用斯里兰卡农场数据验证了随机前沿分析优于修正普通最小二乘法。
Various procedures have been used for the measurement of firm‐specific technical efficiency. Most commonly used methods are static and deterministic. Deterministic methods tend to yield biased estimates of technical efficiency and to overestimate the variability of technical efficiency over time. These conclusions are illustrated by applying stochastic frontier production function analysis and corrected ordinary least squares procedures to farm data from Sri Lanka.
